Abstract: An arrangement for reducing a DC field component in the core of a transformer includes a compensation winding magnetically coupled to the core of the transformer, and a DC generator arranged in series with the compensation winding and with a reactance dipole. The reactance dipole is formed from a parallel circuit of an inductance and a capacitor to feed into the compensation winding a compensating current opposite in sense to the DC field component in the core. The inductance is formed from magnetically coupled first and second windings having N1 and N2 turns respectively, such that N2/N1<1. The first winding is connected on one end to the DC generator and on the other end to the compensation winding. The second winding is connected in parallel with the capacitor. The magnetic coupling of the first and second windings is established via a soft magnetic core having an air gap.

The switching unit can be controlled by a regulating variable provided by a control device and can be switched into a conductive state during a predefined time interval and in accordance with the regulating variable, the switch-on time being mains-synchronous. A device for limiting the current in the current path is provided and the sensor signal is fed to the control device.

Abstract: A technique is provided for detecting a magnetic characteristic variable in particular the magnetic field strength in a section of a core permeated by a magnetic flux. A portion of the magnetic flux is branched off from the core and passed via a magnetic shunt branch, in which at least one non-ferromagnetic gap is formed. A shunt part is disposed in the shunt branch, wherein the magnetic material of the shunt part is not saturated. At least one section of the shunt part is wound with at least one sensor coil in which the branched-off portion of the magnetic flux generates a sensor signal by induction. The magnetic characteristic variable is determined from the branched-off portion of the magnetic flux or a variable derived therefrom using a sensor and evaluation device to which the sensor signal is fed.

Abstract: A joint for two flat structural members, in particular floor panels, wherein a groove and tongue joint joining two flat structural members is provided functionally separate from a twistlock locking the two flat structural members. The twistlock is formed on one of the structural members, is spaced apart from the groove and tongue joint, and engages with a correspondingly formed engaging element of the other structural member. The locking is preferably formed both at the longitudinal edges and at the front edges of a rectangular structural member, such as a floor panel. The locking allows for a joint of the floor panels to occur in flat position, i.e. without twisting.
